Cabinet door mechanism and biological safety cabinet
The invention relates to the technical field of biological safety cabinets, and discloses a cabinet door mechanism which comprises a body, a counterweight structure and a driving structure, the body comprises a door frame and a glass door, and the glass door is installed in the door frame in a liftable mode; the counterweight structure is connected with the upper part of the glass door; the driving structure comprises a pedal rotating wheel and a connecting assembly, the pedal rotating wheel is located below the body, one end of the connecting assembly is connected with the lower portion of the glass door, the other end of the connecting assembly is hinged to the pedal rotating wheel, the position of the connecting assembly changes along with rotation of the pedal rotating wheel, and the driving structure enables the connecting assembly to generate displacement through rotation of the pedal rotating wheel. And the glass door is driven to move upwards or downwards. According to the cabinet door mechanism disclosed by the invention, the contact between the hands of a laboratory technician and a glass door handle can be reduced, so that the pollution to the hands is reduced, the force application burden when the laboratory technician opens a door is reduced, the reliability of equipment is enhanced, and the production cost of the equipment is reduced. The invention further discloses the biological safety cabinet.
本申请涉及生物安全柜技术领域，公开一种柜门机构，包括本体、配重结构和驱动结构，本体包括门框和玻璃门，玻璃门可升降安装在门框内；配重结构与玻璃门的上部连接；驱动结构包括脚踏转轮和连接组件，脚踏转轮位于本体的下方，连接组件的一端与玻璃门的下部连接，连接组件的另一端与脚踏转轮铰接，并随脚踏转轮转动而进行位置变化，驱动结构通过脚踏转轮旋转使连接组件产生位移，带动玻璃门进行上移或下移。本公开的柜门机构实验员能够减少手部与玻璃门把手进行接触，从而减少手部受到的污染，减轻实验员开门时的施力负担，增强了设备的可靠性，降低了设备的生产成本。本申请还公开一种生物安全柜。
